AUTOMATlC BOILER CLEANER.

ffiPECIPICATION forming part of Letters Patent I 1'0.344,925, dated July6, 18186.

Application filed February 25, 1886. SerialNo. 193,248. (No model.)

To all whom it may concern:

Be it known that I, HENRY Suns, a citizen of the. United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new. and useful I1nprovements in AutomaticBoiler-Cleaners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it ap pertains, to make and use thesame, reference being had to the accompanying draw- 1ngs, and to theletters of reference marked thereon, forming part of this specification.

My invention relates to boiler-cleaners; and it consists in theimprovements hereinafter set forth and explained.

My invention is illustrated inthe accompanying drawings, in which Figure1 is a View, partly in elevation and partly in section, of my invention,showing the same attached to a boiler. Fig. 2 is a perspective view of aportion of my invention and of a section of the boiler to which it isattached, portions of the boiler being broken away, showing theopeirmouthed pans and their arrangementin the boiler, and also thearrangement of the discharge-pipe supporting the same.

Like letters refer to like parts in all the figures.

In constructing my improved boiler-cleaner, I make one or moretriangular open-mouthed covered pans, A, according to the size of theboiler B, in which they are to be placed. The mouths of the pans A aremade wide enough to occupy as much of the width of the boiler B at thenormal level of the water therein as possible, and the mouths of thesepans are made of suiiicient height, so that they will embrace thehighest and lowest normal level of the water in the boiler. The bottomsof the pans A are placed nearly or quite level. The tops, however, slopefrom the open mouths thereofdownward, and the perpendicular sides towardeach other to the points 00, where they are coupled toa T, D, on thedischargepipe E, which projects through the top of the boiler B. Thesepans A may be made in sections, of any suitable and convenient size,which can be readily insertedthrough'the manhole of a boiler, and boltedtogether after they are inside of the boiler. The pans A are locatedpreferably as near as possible to the back end of the boiler 13, withtheir open months toward the front end of the boiler and toward thepoint where the fced-water pipe discharges, which I preferably locatenear the surface of the water in the boiler, directly in front of theopen'mouths of the pans A.

At the rear of the boilerarch, or at any convenient point, I place anupright settling-tank, F, which is of any convenient height; but Ipreferably make it so as to extend from the floor to a height equal tothat of the top of the boiler B, substantially as illustrated in Fig. 1.I connect the discharge-pipe E by means of suitable connections, E, tothis settling-tank F at a point, G, preferably about one-half of thedistance vertically between the top and bottom of the tank F, so thatthe mud and other material discharged from the boiler will settledownward to the bottom of the tank F, where it can be blown off througha blow-off cock, H, placed therein for that purpose, leavingsubstantially clear water above the point G. The connection E of thedischarge-pipe Eis also provided with a cock, G, near the tank F, bymeans whereof the connecting-pipe Fl may be shut off when desired.

At'or near one side of the rear head, B, of the boiler B, I insert adelivery-pipe, Lwhich extends outwardly from the head B ashort distance, where an elbow, J, is coupled thereto, into which a sectionthereof. 1', extends horizontally across the head B a short distancetherefrom to a pointon the opposite side thereof, where by means ofanelbow, J, the connection I is turned back through the rear of the brickarch-work K, from which point, by means of suitable connectionsJ, thedeliverypipe I is connected with the upper end, preferably the top F ofthe settlingtank F. This connecting-pipe I is also provided with avalve, 1, so that it can be shut off when desired. The end of the pipeP, where it eX- tends into the settling-tank F, is preferably providedwith a screen, L, to prevent light particles of matter which have beenonce discharged into the settling-tank F from being drawn back into theboiler.

The operation of my improved boiler-cleaner is automatic, it beingoperated by means of the action of the fire upon the section I,crossingthe rear boiler-head, B, which superheats the water therein, therebyproducing a our- ICO rent from the top of the settling-tank F into thebottom of the boiler, which operates to draw the water and impuritiesraised to the surface thereof by the operation of boiling into the pansA, from whence it is conveyed through the discharge-pipe E and itsconnections E into the settling-tank at G,this action being constantwhile the boiler is being operated. The water in the tank being coolerthan that-in the boiler, the impurities held in suspension are speedilyprecipitated to the bottom of the settling-tank F by the cooling of thewater, leaving the water in the upper part of the tank F, where it isbeing conveyed back to the boiler by the pipes I and I, comparativelyfree from impurities, so that I am enabled to practically remove thegreater part if not all of the impurities from the water, without theintervention of a separate heater or other device than that hereinbeforedescribed.

I am aware that devices having some of the characteristics of myinvention have been heretofore constructed for example, the device ofKemp,shown in his Patent No. 166, 782, dated August 17, 1875. Thisdevice,however, differs materially from my invention, both in itsconstruction and operation, viz: In Kemps device the settling-tank is acomparatively shallow tank, located above or on the top of the boiler,having its inlet and outlet pipes entering it on the same level, nomeans being provided for superheating any portion of the outlet pipe onits return to the boiler. Again, the funnel ends of Kemps outletpipeshave comparatively little skimming capacity, and that capacity isconstantly varying with the height of the water in the boiler, while inmy device the settling-tank is located at one end or beside the boiler,and is of very considerable depth vertically, and has its inlet-pipenear its center vertically, and an outlet-pipe at its top, whichcutlet-pipe passes through the fire-chamber, entering the boiler nearthe bottom at its rear end,

whereby it is superheated. The pans in my device also differsubstantially from Kemps in both shape and operation. Their sides beingvertical, much wider pans may be used, and their skimming capacity isalways the same without regard to the height of the water in the boiler.

In the construction shown I show a convenient construction andarrangement of the the parts of my device, and suitable means forconnecting the parts together; but these may all be varied to suit theshape or location of the boiler to which they are to be applied withoutdeparting from the spirit of my invention.

Having thus fully described my invention, so as to enable others skilledin the art to which it appertains to construct and use the same, (what Iclaim as new, and desire to secure by Letters Patent of the UnitedStates, is-

1. The combination, in an automatic boilercleaner, of one or morecovered pans opening at one end,and located in the boiler about thewater-level, substantially as shown, with an upright settling-tankprovided with ablow-off cock near the bottom thereof, and a pipeconnecting the ends of said pans in the boiler with the said tank at ornear the center vertically ofthe tank, and also a pipe extending fromthe upper end of said settling-tank across the firechamber and into therear end of the boiler near the bottom thereof, substantially as and forthe purpose set forth.

2. The combination, in an automatic boilercleaner, of one or moretriangular covered pans open at the large ends thereof, and located inthe boiler about the water-level, substantially as shown, with anupright settlingtank provided with a blow-off cock near the bottomthereof, and a pipe connecting the small ends of said triangular coveredpans in the boiler with said tank at or near the center vertically ofthe tank, and also a pipe in the upper end of said tank provided with ascreen and extending therefrom into the fire-chamber and acrossthe rearend of the boiler, and entering the same at or near the bottom thereof,substantially as and for the purpose set forth.

3. In an automatic boiler-cleaner, the triangularflat-bottomed andperpendicular sided covered pans A, the T D, connected to the small endsof the pans A, and the dischargepipe E, in combination with the boilerB, substantially as and for the purpose set forth.

4. In an automatic boiler-cleaner, the upright settling-tank F, having ablow-off cock, H, near the bottom thereof, and an ingresspipe enteringthe same at G, and an egress-pipe near the top of said tank F, allsubstantially as and for the purpose set forth.

5. In an automatic boiler-cleaner, the combination, with the uprightsettling-tank F, of an egress-pipe near the top thereof provided withthe screen L, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
